Earlier this week I received an ad from Kalmbach publishing (they’re the same folks that print Astronomy Magazine) about a super deal they had on their “Wonders of Science” calendar. It only cost $3.88 plus $2.95 shipping.

That’s not bad for a full color calendar with a nice assortment of science photos, so I ordered one and received it today! Great!

However, when I was thumbing through it and got to April…..well, “Houston, we have a problem”.

Just look at the description below April 20….

Never mind that the Lunar Landing IS marked on July 20 a few months later….

Maybe this is why the calendar was on sale. If the print is too small to read, just click on the calendar for a larger view.
